WASHING MACHINE Filed Sept. 14, 1925 UNI TED ST T FF C GEORGE 1?. ANSTISS, OF OAK PARK, ILLINOIS, ASSIGNOR TO G. S. BLAKESLEE & CO., OF

CICERO, ILLINOIS, A CORPORATION OF ILLINOIS WASHING MACHINE Application filed September 14, 1925. Serial No. 56,297.

My invention relates to washing machines, and primarily to those of the type shown in my pending application for Letters Patent,

\ proved water directing means;

Serial N 0. 671,788, in which the articles to be washed, such as castings, or other metal articles, automobile fenders, running boards, &c., or dishes, are moved through the machine on an endless conveyor, and while passing therethrough are washed by the throwing of the water, usually containing a cleansing agent in solution. forcibly against them. In

some machines of this type the articles to be washed are continuously in motion while the washing is being done, and in others they are stationary at that time, and my present invention contemplates washing articles handled in either way, although I have chosen to show it embodied in a machine in which the articles are moved continuously during the washing operation. The improvements which form the subjectanatter of my present application have to do with the means for forcibly directing the water against the articles to be washed so that all parts of such articles will be thoroughly cleansed during their passage through the machine. I have shown only such part of the washing compartment of a washing machine as will enable one to understand the invention, but it will be understood that if desired a rinsing compartment, suitably separated from the washing compartment so as to prevent contamination of the rinsing water, may be employed if desired, and the same means used for rinsing purposes.

In the drawings,

Fig. 1 is a sideelevation of a portion of a washing machine equipped with my im- Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1

Fig. 3- is an enlarged vertical sectional view through one of the water throwing nozzles; and

Fig. 4 is a perspective view of the adjust able water throwing tip of the nozzle.

The machine illustrated is in the form of a box-like structure, preferably of sheet metal,

. the lower portion of which serves as a tank adapted to contain wash water, and also rinsmg water where rinsing is to be done in which case two tanks are provided suitably separated from each other. As shown, said machine comprises a casing 5, in the lower.

conveyor so that it travels over the tank 6 are not illustrated as they form no part of my present invention, and any means suitable for the purpose may be employed.

For supplying water under pressure, to be thrown forcibly upon the articles to be washed, I provide a pump 9, preferably of the centrifugal type, which is driven by a motor 10 disposed at one side of the machine, as shown in Fig. 1, the armature shaft of the motor being directly connected to the pump by a shaft 11. .The intake side of the pump is connected to the lower portion of the tank 6 by a suitable pipe, while the discharge side thereof is connected by a pipe 12 with a vertical header 13, the ends of which are provided with horizontal pipes 14 which extend transversely of the machine respectively above and below the path of the articles to be washed, as shown in Fig. 1. Connected to each of. the pipes 14 at opposite sides thereof, by suitable headers 15, are two sets of -horizontally disposed distributing pipes 16 4 upper and lower sets of pipes 16, respectively,

through a plurality of nozzles 17 with which each of said pipes is provided, the nozzles in the upper set of pipes being applied to the under surface thereof, while those applied to the lower set of pipes are at the upper sides thereof. Each of said nozzles is constructed in the manner best shown in Fig. 3, and comprises a body portion 18 within which is defined a socket which is cylindrical in form and open at one end, while at the other end it converges to an integrally formed threaded nipple 19 by which it is connected with the pipe 16. Fitted in the body portion 18 so that it rests upon. the tapered walls of the inner end thereof is a collar 20, the outer margin of which forms a seat for the globular inner end portion 21 of an adjustable tip 22 through which the water supplied to the nozzle is discharged. The outer end portion 23 of the tip is in the form of a tube flattened at its outer end, as shown in Fig. 4:, to provide a broad narrow opening through which the water is discharged. It will be evident that by this construction a tight connection is provided between the globular portion of the tip and the seat 20 which prevents the escape of water between them, and that the tip may be adjusted to various angular positions with respect to the body portion 18, or may be turned about its longitudinal axis, without affecting such connection, since whatever position the tip may occupy with respect to the body portion of the nozzle the globular base of the tip always makes close contact with the seat 20. The tip may, therefore, be adjusted to discharge the water in a multiplicity of directions, and also by rotating the tip the form in which the jet of Water strikes the article against which it is directed may be varied to meet special conditions. It will be obvious from the foregoing that by providing the pipes 16 with nozzles of the character described the machine is Well adapted for use in washing articles of a variety of shapes because the independent adjustability of the nozzletips makes it possible to arrange for the forcible application of the water at the points where it is'needed to eifect thorough cleansing of the articles being washed. The several tips are held in the position to which they may be adjusted by means of set screws 24L mounted in the body portion 18 and extendingjtherethrough so that their inner ends engage the globular faces of the tips, as shown in Fig. 3, thereby clamping such globular portion against the cylindrical inner wall of the body portion 18. By this means the set screws are effective to hold the tips in position regardless of how they may be set. It will be apparent also that the tips are readily removable without disturbing the body portion of the nozzles, since by loosening the set screw 24 the tip may be lifted out of the recess in which it fits without removing or disturbing any other parts,

and the same is true of the collars 20. Tips having discharge op'enin s of different sizes or shapes may, therefore, e easily applied to the nozzles.

So far as I am aware I am the first in the water under pressure is directed against the articles to be washed by means of a plurality of nozzles having tips adjustable to throw the water in various directions. Also I believe myself to be the first to provide a nozzle having a tip mounted in the manner described so that it is substantially universally adjustable. The claims hereinafter made are, therefore, to be construed accordingly. Furthermore, while it is advantageous to flatten the outer. end of the tubular portion of the nozzle, as described, I wish it to be un derstood that except in so far as that construction is specifically claimed, my invention is not limited to providing the nozzle with the flattened opening.

lVhat I claim as my invention and desire to secure by Letters Patent, is-

1. A nozzle comprising a body portion adapted to be connected with a water supply pipe, a cylindrical socket defined insaid body I 2. A nozzle comprising a body portion.

adapted to be connected with a water supply pipe, a socket in said body having its side walls defined by substantially parallel lines and having one end open, a tip having a globular base of substantially the same diameter as said socket and seated in said socket, and a set screw entering the side wall of said body portion and adapted to engage said globular base for holding the tip in different positions of adjustment.

3. A nozzle comprising a body portion adapted to be connected with water supply pipe, a socket defined in said body portion by substantially parallel elements, one end of said socket being open and the other end communicating with a conical passage formed in said body portion, a removable ring seated in said conical passage, a tip having a globular base insertible through the open end of said socket engaging the parallel elements thereof justment, said body portion having an open end through which said globular base can be removed simply by thereleasing of said set screw.

5. A nozzle comprising a body portion adapted to be connected with a water supply pipe, a cylindrical socket defined in said body portion,-one end of said socket being open and the other end communicating with a conical passage formed in said body portion, a removable circular ring seated in said conical passage, a nozzle tip having a globular base insertible through the open end of said socket and seating on said ring, the outer peripheral edge of said ring having circular line contact with said conical passage to prevent leakage between said ring and passage, the spherical surface of said globular base having circular line contact with the inner peripheral edge of said ring to prevent leakage between said globular base and ring, and releasable means for holding said nozzle tip and said ring in said socket, said nozzle tip and ring being removable through the open end of said socket upon the release of said releasable means.

6. A nozzle comprising a body portion adapted to be connected with a water supply pipe, a cylindrical socket defined in said body portion, one end of said socket being open and the other end communicating with a conical passage formed in said body portion, a removable circular ring seated in said conical passage, a nozzle tip having a globular base insertible through the open end of said socket and seating on said ring, the outer peripheral edgeof said ring having circular' line contact with said conical passage to prevent leakage between said ring and passage, the spherical surface of said globular base having circular line contact with the inner peripheral edge of said ring to prevent leakage between said globular base and ring, and a set screw passing through the side wall of said socket and engaging said globular base for holding the nozzle tip and ring in said socket, said tip and ring being removable through the open end of said socket simply by the releasing of said set screw.
